Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robotic laser brazing systems face communication delays and lack integrated control and state display capabilities, making it difficult to synchronize wire feeding, laser irradiation, and robot movement accurately, and hindering operators' ability to monitor device states collectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external devices like PLC are used to control laser oscillator and wire feeder separately from robot controller, then device control functionality is achieved, but communication delay occurs and synchronization accuracy deteriorates
Solution Approach 1:
The patent merges the control functions of the laser oscillator and wire feeder into the robot controller by providing communication interfaces directly on the robot controller. This allows all devices (robot, laser oscillator, wire feeder, gas supply device) to be controlled through a single centralized controller, eliminating communication delays between separate controllers and improving synchronization accuracy.
2Ease of operation
If separate controllers are used for robot and other devices, then control functionality is distributed, but collective state display becomes impossible and operator monitoring capability deteriorates
Solution Approach 1:
The patent combines the display function for monitoring all device states into the robot controller. The display unit on the robot controller can collectively display states of the robot, wire feeder, gas supply device, and laser oscillator, eliminating the need for multiple separate display systems and improving operator monitoring capability.
3Adaptability or versatility
If multiple separate controllers are used, then device control is distributed, but the number of controllers increases and system complexity increases
Solution Approach 1:
The robot controller is designed with multi-functionality, serving as both the robot controller and the control device for the laser oscillator and wire feeder. By integrating communication interfaces for these devices into the robot controller, the system reduces the number of separate controllers while maintaining control flexibility through a unified control platform.
